However, from the viewpoint of the user, there is a problem that it can not be known how much the fan rotation speed control has the optimum fuel gas consumption efficiency in the situation inside the restaurant.

The movable table number selection mode and the cooking object weight selection mode are based on this problem. The user inputs the quantity information of the table currently being operated in the movable table quantity selection mode or the weight information of the cooking object in the cooking object weight selection mode, When the information is inputted, the inputted information is transmitted to the harmful gas re-combustion unit 1, and the controller 60 calculates the appropriate fan rotation speed based on the received information to control the fan rotation speed of the pressure transfer unit 30 do.

To this end, the controller must previously store the relationship between the amount of the harmful gas generated by the number of movable tables, the weight information of the object to be cooked, and the minimum fan rotation speed for removing the harmful gas.

In the embodiment of FIG. 6, a wireless remote controller is used in consideration of convenience in use, but it is obvious that the user control signal can be transmitted to the harmful gas re-emission device 1 in a wired manner.

In another embodiment of FIG. 7, the POS terminal installed in the store is linked with the harmful gas re-burning device to more effectively control the fan rotation speed of the press-feeding unit.

To this end, the harmful gas re-burning apparatus 1 is provided with a communication unit 50 for receiving an external control signal, and the communication unit 50 is electrically connected to the POS terminal 80 located in the store for communication.

Since the POS terminal 80 basically stores order information for each table, it can use it as weight information of a cooking object for each table. Accordingly, the POS terminal 80 generates the type, area, and weight information of the cooking objects being cooked in the table in the store for each table and transmits them to the communication unit 50. The controller 60 transmits the type, And transmits the fan drive control signal to the pressure feeding unit (30) based on the type, area, and weight information of the object to be cooked for each table received from the controller (80).

According to various reports, it is known that in the case of roasted flour, the fine dust emission concentration varies depending on the type and location of meat. Therefore, when the POS terminal 80 is interlocked with the POS terminal 80, it is possible to know not only the weight information of the object to be cooked, but also the type and the location information.

For this purpose, the controller shall have stored in advance the relationship between the amount of harmful gas generated by the type of meat and the weight of the object to be cooked, and the minimum fan rotation speed for removing it.
